Green issues have been debated in the election like never before, so what does it mean for the Welsh environment?
It is an area that is largely devolved to Cardiff Bay so the promises made in a UK general election would not usually be as relevant here.
But this time it is different because of two massive challenges facing the next government in Westminster - climate change and Brexit.
What do the parties say about emissions?
Starting with emissions, the greenhouse gases that are driving global warming.
The Welsh Government recently announced it would set a new, legally binding target for a 95% cut in emissions by 2050.
It followed advice from the independent Committee on Climate Change, who said that would be an appropriate contribution to the UK as a whole reaching a 100% target - known as "net zero" - by the same year.
Some are still taking it a bit more seriously than others but at least they're all thinking about it
It said Wales "could not credibly reach net zero by 2050" because it had less land available for capturing carbon through tree planting and relatively high agricultural emissions, an industry important to its rural economy.
But now many of the parties fighting for your vote at the election say emissions must be cut sooner.
Plaid Cymru and the Green Party would like to reach net zero by 2030, with Labour pledging to do so during that decade and the Liberal Democrats by 2045.
The Conservatives have stuck with the 2050 target that was announced under Theresa May, still one of the most ambitious put in place anywhere in the world.
If the UK goal changes, it follows that the Welsh target would also have to be revised.
And whatever the deadline, eliminating greenhouse gases from our economy and way of life will mean huge upheaval.
Just last week the Centre for Alternative Technology in Machynlleth published a big report about what would need to happen.
No more petrol and diesel cars, gas boilers ripped out and replaced with greener alternatives, and much, much more renewable energy generation.
Wales will receive a funding boost based on how much is allocated in Westminster for all of this, and as you can see here - how much the parties are pledging varies significantly.

What about green energy?
It is worth paying attention to pledges on energy because the UK government still has powers over any larger schemes (over 350 MW) proposed in Wales.
Things like offshore wind farms, tidal lagoons or nuclear power stations - with different parties favouring different approaches.
Labour, Plaid Cymru, the Green Party and Lib Dems all want to see tidal lagoons - like the stalled Swansea Bay scheme - as well as investing in other renewable forms of energy like solar and wind.
The Conservatives will not support wind farms on land - despite their low cost - but are proposing more out at sea.
