Seasonal produce refers to the times of year when the harvest or the flavour of a given type food is at its peak. This is usually the time when the item is harvested. It appeals to people who prefer a low carbon diet that reduces the greenhouse gas emissions resulting from food consumption otherwise known as food miles.  To encourage seasonal eating you can follow a seasonal eating calendar. Learn more.

Sustainable is a difficult word to define. In simple terms it means that something can be maintained at a certain rate or level indefinitely. In relation to the environment, sustainability means meeting our present needs in a way that does not compromise the ability of future generations to meet their needs.

Example: Solar energy from the sun is sustainable. As long as the sun keeps rising we have access to an indefinite source of energy. This is referred to as a renewable energy. On the other hand oil, gas and coal are not sustainable sources of energy as they will run out one day.

Sustainable living can be experienced as an art; the art of living heartfully and mindfully, paying close attention to how our habits and behaviours impact on the environment and one another.

The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are the 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries - developed and developing - in a global partnership.

The 17 Sustainable Development Goals include:

1. No Poverty (7 targets)
2. Zero Hunger (8 targets)
3. Good Health and Well-being (13 targets)
4. Quality Education (10 targets)
5. Gender Equality (9 targets)
6. Clean Water & Sanitation (8 targets)
7. Affordable & Clean Energy (5 targets)
8. Decent Work & Economic Growth (12 targets)
9. Industry, Innovation and Infrastructure (8 targets)
10. Reduced inequalities (10 targets)
11. Sustainable Cities & Communities (10 targets)
12. Responsible Consumption & Production (11 targets)
13. Climate Action (5 targets)
14. Life Below Water (10 targets)
15. Life on Land (12 targets)
16. Peace, Justice & Strong Institutions (12 targets)
17. Partnership for the Goals (19 targets)

At the Green Centre we use the 10 One Planet Living principles to guide our work. Incidentally the Sustainable Development Goals grew out of the One Planet Living Goals. We find the 17 SDG goals and 169 targets too difficult to remember and the 1,348 publications and 7,835 actions overwhelming. We prefer the simplicity of One Planet Living.
