Bristol will have credibility on green issues (in fact all issues are green issues) when it can demonstrate significant progress on tackling the key issues: horrendous traffic congestion; ongoing air pollution problems; carbon footprint many times higher than is sustainable; ecological footprint that will grow with loss of green spaces and green belt, new road building, rising population...; poor public transport services; low level of economic self-reliance, especially food and energy security; high levels of inequality; poor levels of participation in key matters such as voting in local elections....
That it is thought that a festival is what will make Bristol's green credibility real speaks volumes. A festival on its own is mere flim-flam, nonsense and humbug. When are genuinely and significantly green outcomes going to happen in place of the tinkering and public relations ?? After all people have been burbling their greenwash for decades now.
