All buildings and structures should be zero carbon (powered by renewable energy), preferably from day 1 of occupation but certainly by 2020 at the latest. Renewable energy can either be generated on site or purchased from a dedicated off-site source representing new renewable energy capacity (so that we are adding to total renewable energy capacity, not diverting it from other uses).Country specific agreements on the profile to meet the 2020 target can be negotiated, but the profile must demonstrate rapid and clear progress towards the zero carbon target, especially given current rapid advances in the introduction of renewable energy technology globally.

All buildings and structures are designed or retrofitted to be energy efficient to country-specific best practice standards. Where such standards don't exist, apply a suitable standard from a neighbouring country within the region.

Although nuclear fission may be a bridging technology to reduce climate change in the medium term, it is not considered a renewable energy source for the purposes of OPL. Similarly, although use of fossil fuels with new technologies may be a useful way or reducing carbon dioxide emissions, e.g., on-site gas Combined Heat and Power systems, such solutions are not considered suitable for the purposes of demonstrating OPL, even if the resulting fossil fuel emissions from buildings are offset by carbon sequestration (contrast with Sustainable Transport).

Long term the aim is to "eliminate the concept of waste". By 2020, the following targets must be achieved:

• at least 70% of waste by weight generated by residents and commercial operations within the developments should be reclaimed, composted or recycled;
• per capita waste production should be monitored and targets set for reduction in per capita waste
• clean energy from waste plant may form part of the zero waste strategy provided careful monitoring of emissions is in place and international best practice standards on operations are employed
• ideally no more than 2% of waste by weight should be sent to landfill by 2020
• country based best practice standards in waste minimisation during construction should be employed

Country based agreements on the profile to meet the 2020 target can be negotiated, but the profile must demonstrate a rapid and clear progression to the zero waste target especially given current rapid advances in the introduction of waste processing globally.

Country specific differences and locational issues mean that it is difficult to set a common international numerical target. Most importantly, whereas industrialised countries will need to reduce carbon dioxide (CO₂) from transport, poor countries may need to increase per capita CO₂ emission from transport, at least in the short to medium term. However, in all cases, the EF arising from transport has to be consistent with the overall EF target of achieving One Planet Living (i.e., living within an EF of 1.5 hectares per person).BioRegional and WWF will agree sustainable transport targets on a case by case basis. These targets will be based on a transport CO₂ per capita and will need to show reduction over an agreed regional benchmark and progression year on year towards a "One Planet Living" level. Given the CO₂ contribution from transport in industrialized countries, these targets are likely to be very stretching. A simple sampling process for residents to monitor against this target must be developed.

Targets for travel within the site and to and from the site need to be set, in particular for projects with a major tourist component. For developments with a tourist component, CO₂ per person per night can be used as an indicator.CO₂ emissions from all remaining transport should preferably be offset by a certified carbon sequestration scheme, ideally meeting the WWF Gold Standard reference. For tourist projects, all air travel to and from the site must be offset by a certified carbon sequestration programme. Moreover, no OPL partner may formally oppose introduction of taxes on aviation fuel.

Via the common process guidelines detailed below, country-specific targets should be determined to increase and optimise the use of local, reclaimed, renewable, recycled and low environmental impact materials for construction and estate management phases of the development.

Healthy diets high in local, seasonal, organic and low environmental impact foods should be promoted, given their consistency with a One Planet Living EF.

By 2020, a significant proportion of food should be locally sourced from low environmental impact farming with reduced packaging from a radius of 50 to 100 km from the centre of the site. Given the importance of food to eco-footprints, stretching targets are essential to achieving OPL. Specific targets will be set via the process guidelines detailed below, but a minimum target of 25% of food by weight must meet these criteria, and ideally 50% of food by weight.

Key Performance Indicators should be set for certified organic and fair trade food.

Country specific profiles to hit this target need to be agreed.

Country-specific best practice standards in water efficiency and recycling must be agreed, following the process guidelines detailed in section 4.3.2 above. These targets will need to be stricter in areas with water shortage problems. All residents must have access to safe potable water. Projects in areas of flood risk should have an acceptable 100 year flood risk strategy.

The development must make a net positive contribution to local native biodiversity and natural habitats. Any key species must be identified and monitored, as part of a local conservation plan. A site-specific action plan to maintain, enhance or revive valuable aspects of biodiversity must be elaborated, following the process guidelines detailed below.

At least one opportunity must be identified to regenerate degraded local natural resource stocks (soils, trees, fisheries, etc) and a plan implemented. At least 2 case studies should be showcased, one for biodiversity and one for natural resource stocks.

A site specific action plan to maintain, enhance or revive valuable aspects of local culture and heritage (including anything from local buildings and building techniques to local produce or arts and crafts) must be produced, following the process guidelines detailed below. At least 2 case studies should be showcased.

OPL communities are expected to improve the welfare of selected disadvantaged populations, whether on site or elsewhere. Country-specific priorities of equity and fair trade must be identified and targets set, following the common process guidelines detailed below. Where products are imported from developing countries, targets should be set for the proportion that must be certified fair trade [1]. At least 2 case studies should be showcased.

A plan for promoting the health and happiness of residents must be produced, building on emerging findings from happiness research, following the process guidelines detailed below. Residents' satisfaction levels and concerns must be regularly monitored. Partners should also explore the feasibility of meeting UN standards for health, security and environmental quality. At least 2 examples of strategies to promote health and happiness must be showcased.
