Agricultural Worker Categories
There is a lack of clear-cut distinctions between different categories of workers. Consequently, there are numerous types of labour relations and different forms of labour force participation. The different categories of workers also vary within each country and, in certain cases, a single farmer may be grouped in more than one category. Many smallholders supplement their income with wages earned by working in large commercial farms during harvesting periods.
ILO
Summary of broad categories of agricultural workers:
append2
ILO. Safety and health in Agriculture document
Child
Any person less than 15 years of age, unless local minimum age law stipulates a higher age for work or mandatory schooling, in which case the higher age would apply. If however, local minimum age law is set at 14 years of age in accordance with developing country exceptions under ILO convention 138, the lower age will apply.
ILO
The ILO Minimum Age Convention, No. 138 (1973) states that the minimum age of employment should not be less than the age of completion of compulsory schooling and, in any case, shall not be less than 15 years. However a Member country whose economy and educational facilities are insufficiently developed, may under certain conditions initially specify a minimum age of 14 years.
ILO
Child labour
Any work by a child younger than the age (s) specified in the above definition of a child, except as provided by ILO recommendation 146
ILO
Young worker
Any worker over the age of a child as defined above and under the age of 18. 
ILO
Worst forms of child labour 
Whilst child labour takes many different forms, a priority is to eliminate without delay the worst forms of child labour as defined by Article 3 of ILO Convention 182.
ILO
Hazardous child labour
Hazardous child labour is defined by Article 3 (d) of the ILO Convention concerning the Prohibition and Immediate Action for the elimination of the worst forms of child labour, 1999 (182) 3D work which, by its nature or its circumstances in which it is carried out is likely to harm the health, safety or morals of children.
ILO
Occupational accident
An Occupational accident is an unexpected and unplanned occurrence, including acts of violence, arising out of or in connection with work which results in one or more workers incurring a personal injury, disease or death. Included in occupational accidents are travel, transport or road traffic accidents in which workers are injured and which arise out of or in the course of work, i.e. while engaged in an economic activity, or at work, or carrying on the business of the employer. Occupational injury: any personal injury, disease or death resulting from an occupational accident; an occupational injury is therefore distinct from an occupational disease, which is a disease contracted as a result of an exposure over a period of time to risk factors arising from work activity.
ILO Resolution/Convention 155 on statistics of occupational injuries (resulting from occupational accidents), adopted by the Sixteenth International Conference of Labour Statisticians, (Oct.1998)  
Occupational disease
A disease contracted as a result of an exposure to risk factors arising from work activity
ILO
Reporting period
This will be one year unless otherwise agreed. The period should include a single complete milling season.
Theoretical recovery of sugar
The theoretical OR (Overall Recovery) normalized for juice purity and cane fibre content is calculated as:
append1
where WF,C is the fibre content of the cane in g/100 g and PJ the purity of the raw juice. In addition, refining all white sugar in a white end refinery is expected to increase the undetermined loss by 0.4 % of the sugar in raw juice. Then the factor 0.98  becomes 0.976.
Sugarcane yield
Irrigated - 85; Supplementary 65; Rainfed 45 (total yield per year/total ha cut/weighted average age at harvest) for each category of water regime. Value for reporting period or 5 year rolling average can be used. Seedcane production (yields and area) should be excluded and non cane areas and roads and contours should be excluded from area harvested. (Supplementary irrigation is where irrigation is used to increase yields obtainable under rainfed conditions).

Phosphate equivalent as a measure of eutrophication
Since phosphorus and nitrogen differ in their eutrophication effects, a phosphate equivalent conversion is used based on potency factors of 3.06 for phosphorus and 0.42 for nitrogen. Using 120 kg N /ha/y and 20 kg P /ha/y, the figure would be (120 x 0.42) + (20 x 3.06) = 112 kg phosphate/ha/y.

High Conservation Value

High Conservation Value (HCV) areas are defined as natural habitats where conservation/ biodiversity values are considered to be of outstanding significance or critical importance based on factors such as the presence of rare or endemic species, sacred sites, or resources harvested by local residents (see www.hcvnetwork.org). For implementation of the Bonsucro standard each country is required to provide a country specific and official interpretation of High Conservation Value which will be used for audits in that country. A cut off date of 1 January 2008 will apply. 
The six High Conservation Values (HCVs):
HCV 1 Areas containing globally, regionally or nationally significant concentrations of biodiversity values (e.g. endemism, endangered species, refugia)
HCV 2 Areas containing globally, regionally or nationally significant large landscape level forests, contained within, or containing the management unit, where viable populations of most if not all naturally occurring species exist in natural patterns of distribution and abundance
HCV 3 Areas that are in or contain rare, threatened or endangered ecosystems
HCV 4 Areas that provide basic services of nature in critical situations (e.g. watershed protection, erosion control)
HCV 5 Areas fundamental to meeting basic needs of local communities (e.g. subsistence, health)
HCV 6 Areas critical to local communities’ traditional cultural identity (e.g.areas of cultural, ecological, economic or religious significance identified in cooperation with such local communities).

Also includes soils with a large risk of significant soil stored carbon such as peat lands, mangroves, wetlands and certain 100% native and natural grassland (that were never modified by human activities).

Significantly affected
A significant impact would be apparent if the operations of sugarcane farms or mills resulted in changes to the environment that resulted in (1) the quality and / or quantity of habitat supporting an endangered or threatened species being affected to the extent that the numbers and viability of the species (the classification from the IUCN red list) was adversely affected;  (2) conversion, diminution or degradation  of the integrity of an endangered habitat  such that there was a measurable adverse impact on its ecological status in the opinion of a competent ecologist  (3) ecosystem service (such as water supply) being sufficiently changed as to cause material adverse impacts to local communities or ecosystems (for example, flows contain additional nutrients that change downstream ecology or affect the availability of drinking water for downstream communities).
 
Conducting business with integrity
Businesses should work against corruption in all its forms, including extortion and bribery.
Principle 10 UN Gobal Compact
Forced or compulsory labour
This shall mean all work or service which is exacted from any person under the menace of any penalty and for which the said person has not offered himself voluntarily  
ILO Convention C29
Most common forms of forced or compulsory labour: Forced labour can take many forms – some imposed by the State, but the majority in the private economy…..Forced labour can be an outcome of trafficking in persons and irregular migration… Mechanisms of force applied include debt bondage, slavery, misuse of customary practices and deceptive recruitment systems. Some of the most common forms of forced labour include (for a full list see ILO Handbook):
Combating forced labour: A handbook for employers and business, booklet 2
·         Debt-induced forced labour: Commonly referred to as “bonded labour” in south Asia, where the practice is most common, but also known as “debt bondage”. .. Debt bondage arises when a person mortgages his or her services or those of his family members to someone providing credit in order to repay the loan or advance.
·         Forced labour as an outcome of human trafficking: Trafficking in persons, or human trafficking, is often linked to forced labour. It is fuelled by organised criminal networks or individuals and can involve deceptive recruitment, racketeering and blackmailing for the purpose of labour exploitation.
Forced labour linked to exploitation in labour contract systems: This can be found almost everywhere in the world today. For example, migrant workers can find themselves "bonded" to a labour contractor because excessive fees have been charged and with limited if any possibility to change the employer once they arrive in the destination country.
Discrimination
1. The term discrimination includes—(Art 1 C111)
ILO Convention C111
(a) any distinction, exclusion or preference made on the basis of race, colour, sex, religion, political opinion, national extraction or social origin, which has the effect of nullifying or impairing equality of opportunity or treatment in employment or occupation; 
(b) such other distinction, exclusion or preference which has the effect of nullifying or impairing equality of opportunity or treatment in employment or occupation as may be determined by the Member concerned after consultation with representative employers' and workers' organisations, where such exist, and with other appropriate bodies. 
2. Any distinction, exclusion or preference in respect of a particular job based on the inherent requirements thereof shall not be deemed to be discrimination. 
3. For the purpose of this Convention the terms employment and occupation include access to vocational training, access to employment and to particular occupations, and terms and conditions of employment.

Appendix 3. GHG Calculations

 
Bonsucro Scheme for calculation of greenhouse gas emissions from sugarcane growing and processing 
1. System Boundary 
The operational boundary includes growing and processing of sugarcane. It considers the boundary to include each individual mill and its growers as a unit, rather than a company owning and operating more than one mill. In the case of IPPs (Independent Power Producers) providing steam and power to a mill from bagasse that has been provided by the mill, the IPP is considered together with the mill concerned. The system boundary includes in addition the energy embedded in the manufacture and supply of all fertilizers and chemicals, but excludes the energy embedded in agricultural and milling capital equipment. All the activities of a plant on one site are considered, to reflect the sustainability of the total system producing food, fuel, energy and chemicals.
This analysis represents a B2B analysis, considering the operation of a cane sugar processing facility, producing raw sugar and/or ethanol at the factory gate. Stand-alone refineries are not considered to be within the boundary. It accounts for the provision of products to a third party that is not the end user (cradle-to-gate).
2. Direct and indirect effects
The energy and GHG calculations are associated with direct energy inputs and at a second level by indirect inputs. Direct inputs are mainly fuel and power inputs, expressed in terms of their primary energy value. Indirect inputs include, in addition, the energy required for the production of chemicals, fertilizers and other materials used. The indirect inputs do not include the additional energy necessary for the manufacture and construction of farm, transport and industrial equipment and buildings.

3. Land Use Change
Land use change can be separated into direct and indirect components: 
• Direct land change refers to a change from the original state of the land to use for sugarcane production. Depending on the previous use of the land in question, it is surmised that the land use change can unlock some of the carbon in the existing soil and vegetation. 
• Indirect land use change concerns secondary effects induced by large scale expansion. This displaces existing crops, leading to expansion of crop land elsewhere, either in the same country or in other parts of the world. The effects of these changes are very difficult to estimate. 
If the product’s supply chain directly caused non-agricultural land to be converted to agricultural use on or after 1 January 2008, then GHG emissions associated with the direct land use change are included in the carbon footprint calculation. The table of IPCC default land use change values for selected countries published in the PAS 2050 are used in the calculation.
4. Handling of co-products and multiple products
Two approaches are possible:
•  The “substitution” or “displacement” method attempts to model reality by tracking the likely fate of by-products. Each co-product generates an energy and emission credit equal to the energy and emissions saved by not producing the material that the co-product is most likely to displace. 
•  The “allocation” method allocates energy and emissions from a process to the various products according to mass or energy contents or monetary values. 

In the case of sugarcane processing, a factory exporting power or bagasse achieves a credit in terms of energy and emissions saved, according to the displacement of energy in that country. Some standards recommend the use the grid average GHG intensity to calculate the GHG credit for the exported power, although it may be more realistic to use the marginal energy mix. Since the marginal energy provision is likely to be from fossil fuels, the saving estimate is conservative when using the average generation mix. In this case, the approach aligned with the EU RED is adopted, which states that for calculating exported power credits, the average factor should be used. The country specific table of values used is given in the Annexure.
Where a factory produces only sugar and molasses, the allocation in proportion to market value is adopted; in most cases the allocation to molasses is less than 10 % of the total. Although the prices will change over time, the relative values will be far more stable. It is possible to use a displacement calculation, assuming that molasses displaces certain ingredients in an animal feed. However this is likely to vary significantly in different countries.
In the case of a factory producing more or less equivalent quantities of sugar and ethanol, the split of energy input and GHG emissions between the two products becomes a more difficult issue. The calculation assumes that allocation should be by energy content of the products. Sugar has a calorific value of 16500 MJ/t and ethanol 21 MJ/L; on the basis that 600 L of ethanol are produced from one tonne of sucrose, this implies a sugar equivalent value of 27.5 MJ/L for sucrose. On this basis, 57 % of the emissions should be allocated to sugar and 43 % to ethanol. As an alternative, the calculation procedure also allocates the energy use and emissions on a mass basis on equivalent sugar, on the basis that 1 tonne sugar is equivalent to 600 L ethanol.
In the case of an autonomous distillery, where the only product is ethanol, energy use and emissions are related to litres of ethanol produced or to MJ in ethanol.

5. Components contributing to emissions
CO2 from sugarcane emitted in combustion and in ethanol fermentation is considered zero CO2 emission to the air, because this is the carbon taken in from the air during sugarcane growth. CO and VOCs emitted in combustion are assumed to be converted to CO2 fairly rapidly, but methane and nitrous oxides from burning bagasse are accounted for in GHG emissions. CO2 emissions arising from biogenic carbon sources are excluded from the calculation of GHG emissions from the life cycle of products, except where the CO2 arises from direct land use change.
The greenhouse gases covered are CO2, N2O and CH4. Methane and N2O have global warming potentials 23 and 296 times that of CO2 respectively (IPCC 2007). Greenhouse gas emissions are aggregated on a carbon dioxide equivalent (CO2eq) basis.
Non-CO2 emissions arising from both fossil and biogenic carbon sources are included in the calculation of GHG emissions. In the case of burning bagasse in sugar mill boilers, it is assumed that 30 g CH4 and 4 g N2O are produced per 1000 MJ of energy in the bagasse burnt, based on IPCC data for burning of biomass. Changes in the carbon content of soils, either emissions or sequestration, other than those arising from direct land use change, are excluded from the assessment of GHG emissions. Any GHG emissions arising from transport required during the product and raw materials life cycle are included in the carbon footprint assessment. Emission factors for transport include emissions associated with creating and transporting the fuels required.
6. Calculation method
A materiality threshold of 1 % has been suggested to ensure that very minor sources of life cycle GHG emissions do not require the same treatment as more significant sources.
Both the energy usage and emissions are calculated in the same spreadsheet, since the latter are largely determined by the former. The calculation includes the effects of the manufacture of fertilizer. Farming operations include chemicals application, irrigation, tillage and harvesting (and preparation of cane setts for planting). Cane transport covers getting the cane to the mill. The cane is processed to sugar and molasses or ethanol, and may include export of electric power or bagasse. The energy embedded in the manufacture of milling and other equipment is excluded. Inclusion of energy embedded in capital goods and equipment generally has an effect of less than 10 % on calculated emissions and is excluded. No allowance for transport of products from the factory is allowed for. Transport of workers is not included.
The primary energy is calculated. It differs from the direct energy input in that it takes into account the efficiency of generation and supply of the secondary energy source e.g. using a conversion factor from energy in the fuel used to generate electricity to the energy in the power produced. This applies to power, fuel, steam and any other energy input. The GHG balance is particularly uncertain because of fertilizer nitrous oxide emissions and error margins can be enormous. The use of nitrogen fertilizers results in GHG emissions in two stages: fertilizer manufacture (primarily CO2 emissions from energy used) and fertilizer application (primarily N2O emissions from nitrification and denitrification processes in the soil). The assumption is made that 1.325 % of N in nitrogen fertilizer is converted to N in N2O through nitrification and denitrification, following the IPCC recommendations.
In addition, agricultural lime application results in GHG emissions from both production energy use and in-soil reactions that release CO2. These latter emissions are a further source of uncertainty. The model uses the IPCC factor of 0.44 kg CO2eq/kg lime, which assumes that all C in lime becomes CO2. This is the upper limit; it is possible in weakly acidic soils that limestone results in a net sink of CO2.
The calculation approach adopted in this study is similar to that used in the EBAMM model (Farrell et al. 2006), which itself is similar to the GREET model (Wang et al. 2008). These models have been used in the past mainly to model the production of biofuels from corn, and they have had to be modified for sugarcane to incorporate additional issues as follows:
1.
Modifications to incorporate sugar manufacture as the major activity. This includes power, fuels and lubricants.
2.
Emissions due to cane burning. This is based on IPCC emission factors for burning biomass of 0.07 kg N2O/t dry matter and 2.7 kg CH4/t dry matter.
3.
Allowance for N2O emissions from filter cake, vinasse and cane residue left in the field. This assumes 1.225 % of N in the residue is converted to N in N2O (Macedo et al. 2008).
4.
Emissions of CH4 and N2O in burning bagasse in sugar mill boilers; values of 30 and 4 g /1000 MJ energy in bagasse respectively are used (Wang et al. 2008).
5.
Energy value of process chemicals.
6.
A credit for molasses (where produced) based on its economic value relative to that of sugar.   
7.
Emissions from anaerobic treatment of effluent in the case that methane is not captured and used as a fuel. IPCC guidelines suggest 0.21 t CH4 produced per t COD removed.
8.
Allowance for any imports of molasses, bagasse and/or other biomass.

                             
7. Default and secondary data
Secondary data (obtained from sources other than direct measurement) are used to calculate emissions where primary data are not available or inappropriate, to enable consistency and, where possible, comparability:
 
• Global warming potential of greenhouse gases
 
• Electricity emissions (in kg CO2eq/kWh) from various energy sources
 
• Energy content of fertilizers per kg
 
• Energy use of pesticides and herbicides per kg
 
• Fuel emissions per litre
 
• Waste emissions per kg
 
• N2O and CH4 emissions from burning bagasse
 
• N2O and CH4 emissions from burning cane
 
• Energy embedded and emissions for process chemicals
 
• Direct land use change
 
• Agriculture emissions from soils
Default values used are given in the Annexure.

ANNEXURE DEFAULT VALUES USED

It is expected that some of these default values will change as more accurate or realistic values are published. Further fine tuning may also be incorporated in future e.g. in allowing for different emissions from different types of nitrogenous fertilizer. It may also be necessary to introduce country specific default values where they are seen to make a material difference to the calculations.

Most of the default values are obtained from the EBAMM model (Farrell et al. 2006), often based on the GREET model using data from Shapouri et al. (2004) and Graboski (2002), or from Macedo et al. (2008).

Appendix 5. Detailed parameters to calculate GHG emissions from biofuels set under the EU Renewable Energy Directive (2009/28/EC) and revised Fuel Quality Directive (2009/30/EC) and included in section 6.

 
1.
Annualised emissions from carbon stock changes caused by land-use change after 1 January 2008, el, shall be calculated by dividing total emissions equally over 20 years. Change from one crop to another is not regarded as land use change according to the Communication from the European Commission on the practical implementation of the EU biofuels and bioliquids sustainability scheme and on counting rules for biofuels (OJ C160/8 of 19 June 2010) and therefore annualized emissions (el) are equal to zero.
For the calculation of those emissions the following rule shall be applied:
el = (CSR – CSA) × 3,664 × 1/20 × 1/P (1)
where
el =
annualised greenhouse gas emissions from carbon stock change due to land-use change (measured as mass of CO2-equivalent per unit biofuel energy);
CSR =
the carbon stock per unit area associated with the reference land use (measured as mass of carbon per unit area, including both soil and vegetation). The reference land use shall be the land use in January 2008 or 20 years before the raw material was obtained, whichever was the later;
CSA =
the carbon stock per unit area associated with the actual land use (measured as mass of carbon per unit area, including both soil and vegetation). In cases where the carbon stock accumulates over more than one year, the value attributed to CSA shall be the estimated stock per unit area after 20 years or when the crop reaches maturity, whichever the earlier;
P =
the productivity of the crop (measured as biofuel or bioliquid energy per unit area per year); and
2.
Land carbon stocks are calculated according to the guidelines published by the European Commission, for land converted after 1 January 2008. These are outlined in the Commission Decision of 10 June 2010 on guidelines for the calculation of land carbon stocks for the purpose of Annex V of Directive 2009/28/EC, published in the EU Official Journal L151 of 17 June 2010, p. 19.
TBonsucro will communicate to economic operators any details of lists on protected areas as soon as they are available from the EC.
3.
Additional mandatory requirement for biofuels under the EU Renewable Energy Directive (2009/28/EC), included in section 6 and this Appendix, shall be modified according to the publication by the European Union of new communications and decisions, including on the definition of highly biodiverse grasslands, degraded lands, and new default values for greenhouse gases emissions, as well as any modification related to the EU Directive 2009/28/EC. Article 17.3 c) of the EU Directive 2009/28/EC, states that the Commission shall establish the criteria and geographic ranges to determine which grassland shall be covered by this article. In the absence of decision by the Commission on this topic, no legal interpretation can be given or claimed regarding this concept. This Standard will be modified to encompass the criteria and geographic ranges defined by the Commission as soon as an official communication or decision has been issued.
4.
The fossil fuel comparator for calculation of GHG reductions recommended for use by the EU is 83.8 g CO2eq/MJ. The figure of GHG emissions to appear on Bonsucro EU certificates shall be calculated as follows: SAVING= ((83.8 - Emissions from criterion 6.1) / 83.8) x100 per cent
(1) The quotient obtained by dividing the molecular weight of CO2 (44,010 g/mol) by the molecular weight of carbon (12,011 g/mol) is equal to 3,664.
