[en] The implementation of the EU ETS in 2005 led to the establishment of a price that
enables manufacturers to realize the impact of their activities on the environment clean.
There are no items in this day, since the creation of the European carbon market, which
has focused on the analysis of volatility transmission between different investment horizons.
The purpose of this paper is to fill this gap in the literature. we analyze the
volatility of the price of carbon quota (EUA), by studying linear and nonlinear causal
relationships of wavelet components between the different volatilities that we captured at
different time scales. we initially conducted the decomposition of the EUA price volatility
at different time-frequency interval using a wavelet approach. Our study will be to examine
whether the volatility is transmitted from the high-frequency structure of the carbon
price in the low frequency. Our results show an intra-structural dependance in carbon
price volatility. We detect instability in the volatility of carbon and observe the existence
of a bidirectional relationship from high frequency traders to low frequency traders. Our
study showed that high-frequency shocks yields carbon price can have a significant impact
beyond their Fontiers and touch the low frequency structure associated with long-term
